FIELD: aircraft engineering.
SUBSTANCE: aerodynamic profile of the load-bearing element includes upper and lower contours formed by convex curves and their intersection points with given coordinates relative to the profile chord, and has a rounded leading edge.
EFFECT: improved aerodynamic characteristics of profiles for the middle and butt sections of propeller blades, improved flight data of the aircraft in hovering and forward flight, an acceptable low level of variable and constant loads in the load-bearing system, and aeroelastic stability in a wide range of flight speeds are achieved.
